The enzymedGTPase (EC 3.1.5.1)[1][2] catalyzes the reaction
This enzyme belongs to the family ofhydrolases, specifically those acting on triphosphoricmonoester bonds. Thesystematic name isdGTP triphosphohydrolase. Other names in common use includedeoxy-GTPase,deoxyguanosine 5-triphosphate triphosphohydrolase,deoxyguanosine triphosphatase, anddeoxyguanosine triphosphate triphosphohydrolase. This enzyme participates inpurine metabolism.
As of late 2007, 4structures have been solved for this class of enzymes, withPDB accession codes1HA3,2C77,2C78, and2DQB.
